GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 513,671, dated January 30,1894.

Application filed November 26, 1892. Serial No. 453,182. (No model.)

To all whom it may concern:

Be it known that I, PETER PAUL CoLER, a citizen of the United States, residing at Clyman, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

My invention relates particularly to the gaveling and tripping devices of the binding mechanism which I have simplified and improved as will be hereinafter fully set forth, and its leading feature lies in the employment of the needle-shaft as a means of communicating motion from the trip-arm or compressor at the waist of the bundle to the clutching devices at the front ofthe binder; thus enabling meto dispense with the rockshaft and its connections through which this is usually accomplished.

The accompanying drawings show the application of my improvement to a'grain binder of the well known Appleby type but it may by slight modification in detail Within the skill of any good mechanic be readily applied to other forms of binding mechanism without departing from the spirit of my invention.

Figure l is a plan or top view of so much of a binding mechanism of the type before referred to as is necessary to illustrate the application of my invention thereto. Fig. 2 is a side elevation of the same viewed from the stubble side of the machine. Fig. 3 is a rear end elevation showing in full lines the parts in their normal position. Fig. 4. is a similar view showing the same parts in the position assumed when a bundle is being bound. Fig. 5 is a front end elevation showing the preferred arrangement of the operating gear and trip-clutch mechanism. Figs. 6 and 7 are enlarged detail views of the tripclutch inv sectional elevation and plan respectively.

A is the post-frame of the binder, having overhanging tubular arm, A', for the reception and support of the tyer-shaft and vsubtending tubular arm, A2, in which the needle-shaft rocks, and from which project anges, or feet, a., a', that rest upon and are securely bolted to transverse tie-bars, o, b', connecting the longitudinal pipe-bars, B, B', at the inner and outer sides, respectively, of the binder-frame, rigidly with the post-frame.

A constantly driven packer-shaft, C, is

supported in bearings, c, c', in the transverse tie-bars of the frame, and has keyed to its front end a sprocket-wheel, C', by which to impart motion to the binder.

The tyer-shaft, D, having its bearings in the overhanging tubular arm of the postframe, is provided at its front end With a gear-wheel, D', hereinafter termed the main binder gear, 0r main gear, carrying, as usual, a wrist-pin, d, connected by link or pitman, E, with the end of a crank-arm, e, from the needle-shaft, E, mounted in the subtending tubular arm of said frame.

The main gear meshes with and is intermittently driven by atrip-pinion, F, mounted on a stubaxle,f, which projects from the postframe, and carrying a trip-dog, F, pivoted at f', to its outer face. This dog has an outsetting lug or roller, f2, which is normally urged by the spring, f3, in toward the axis of the trip-pinion, but is thrown out toward the periphery of said pinion by the contact of a tail extension, f4, from the dog, with any suitable stop, or obstruction, as presently explained. When the lug or roller is at the extreme of its inward movement it stands in the path of driving-lugs, g, on the adjacent face or hub of asprocket-wheel, G, mounted alongside the trip-pinion and on the same axle, and Will be struck by one or the other of said lugs, and being pushed before it will cause the trippinion to turn, and thereby the main-gear also, until such time as an obstruction is interposed to the passage of the tail extension when the trip-dog is rocked on its pivot and the lug or roller is thrown out or withdrawn from the path of the driving-lugs, and the trip-pinion thereby disengaged, bringing the binder to rest.

H is the needle rigidly secured to its shaft at the rear end of the subtending arm of the post-frame, andI is the trip-arm or compressor loosely mounted upon the needle-shaft next to the needle and held against endwise movement therealong by means of a pin, 1l, driven through the end of said shaft next to the hub of the trip-arm. Upon a depending piece or heel-plate, ,of the trip-arm, below the needleshaft, and hereinafter termed the trip-cam, is a side projecting lug, t', inclinedor beveled onits front face and normally bearing against the correspondingly inclined rear face of the cam-lug, ft2, fixed-on the binder-frame. The needle-shaft at its front end extends beyond IOO ' its wrist-pin.

the subtending frame arm a sufficient distance to permit of a considerable endwise movement of the shaft in its bearings. Therefore when the grain is accumulated in the receptacle by the action of the packers, J, to such an extent and under such compression as to rock the trip-arm outward on its journal, the inclined face of the lug from the trip-cam or heel-plate of said arm rides past the inclined face of the fixed cam-lug and compels the trip-arm to move laterally, or away from the cam-lug, and push against its retaining pin, thus moving the needle-shaft longitudinally in the same direction.

The link or needle-pitman, by which motion is communicated from the main-gear to the needle-shaft, is loosely mounted upon the wrist-pin of the main-gear to permit of a limited lateral vibration without cramping, its connection with the end of the crank-arm from the needle-shaft also being loose for the same purpose, but of such a nature that this end of the link is compelled to follow the longitudinal movements of the shaft imparted by the rocking of the trip-arm. The Wristpin is of considerable length, and turned down at its outer end, the link-head being mounted on this outer reduced portionJc, and pressed against the shoulder, k', by a spring, K, confined against its outer side by a washer and split key or Cotter. A lug, K', projects rearwardly or toward the binding receptacle from the head of the link, and adjacent to the main-gear is bent forwardly toward the tripclutch to provide a linger or trip-latch, k2, which stands in the path of the tripdog, when the binder is at rest and the packers are acting, toobstruct the passageof the tail extension of said dog, as before suggested, thereby holding the clutch out of engagement with the binder.

Cast upon a forwardly projecting boss from the subtending arm of the post-frame, is a ledge or horn, L, against which the needlelink is pressed by the action of the spring on Now when the trip-arm or compresser is rocked outward, and the passage of the inclined lug on the trip-cam past the opposing cam-lug on the frame forces the needle-shaft endwise in its bearing, the lower end of the link is drawn to the rear and, the horn serving as a fulcrum, the upper end is thrown to the front against the force of the spring coiled around the wrist-pin (as shown by dotted lines, Fig. 2) withdrawing the trip-latch from the path of the trip-dog, and permitting it to engage the driving-pins on the constantly driven sprocket-wheel, thereby starting the binder. The trip-arm being loosely mounted upon the needle-shaft, is free to rock thereon except as restrained by the resistance dog, M, pivoted upon the outer tubular frame-bar beneath the trip-cam and having a finger, m, standing past the periphery of said cam and pressed thereagainst by a spring, m', wound about the periphery of the frame-bar, with one end caught over the pin, m2, and the other hooked to the hub of the dog. The tripcam has on its lower edge or periphery a straight cam-track or resisting surface, n, with a stop-shoulder or hook, n', at its inner end, and a recess or notch, n2, at its outer end,suc ceeded by a projecting guard or tail, n3, curved concentrically, or nearly so, with the axis of the needle-shaft.

As already intimated, and as shown in Fig. 3, the end of the resistance-dog or, what is the same thing, the finger therefrom, bears normally against the straight track of the tripcam, about midway between the stop shoulder and the notch, the spring pressure on the dog being sufficient to hold the tripa-rm up to its work. As the gavel is formed and compressed against the trip-arm by the action of the packers it forces the arm back, depressing the dog against the stress of the spring until its end falls into the socket at the outer extreme of the straight track, where it positively locks the trip-arm, for the time, against further outward movement, that it may act as a compressor. This recession of the triparm moves the needle-shaft endwise, rocks the needle-link and trips the binder into action, as before explained, when the needle will rise, compress the bundle against the trip-arm and encircle it with cord.

In order to undog the trip-arm and allow it to rock down and out of the path of the bundle when it has been bound and is ejected from the receptacle, I employ a curved push-pawl, O, pivoted at o, upon the shank of the needle, and formed at its end with an abrupt shoulder, o', and an overhanging iiange, o2, to catch upon an offset, 0*", from the hub of the dog. In its normal position, that is when the needle is down (see Fig. 3), this push-pawl being held down either by spring, 04, or by gravity, rests about midway of its length, upon the top or edge of the offset and does not engage therewith or interfere with the movement of the resistancedog. The recession of the trip-arm before the inpacking gavel, rocking the resistancedog outward, carries the oifset therefrom along the push-pawl and toward, but not past, the shoulder at its free end, when the ensuing rise of the binder-arm draws the pawl inward, until at the moment the final compression is taking place, the shoulder thereon drops behind, and the flange rests over, the odset. Then, the knot being tiedvand the band severed from the spool end of the cord, the needle recedes, forcing the pawl outward and rocking the dog downward out of engagement with the notch in the trip-cam thus releasing the trip-arm and allowing it to fall beneath the path of discharge for the sheaf. The push-pawl has by this time been brought to such an angle with the odset, by the radial movement of the latter around the axis of the dog, that it readily slips past and rides over the edge of said offset, and being thus disengaged therefrom, oers no resistance to the return of the dog to normal position, but

such return is prevented until the proper time by the outsetting curved guard from the trip-cam, which rests upon the end of the dog and keeps it depressed until the sheaf is clear of the trip-finger, whenv the shank of the needle strikes the inner end of the lateral lug from the trip-cam and forces the latter outward until the trip-linger has been restored to position and the resistancedog is again resting at its normal point along the straight track. The needle, which has passed below vits normal position in this action, now is lifted to such position by the passage of its pitman past the dead center, thus leaving room for the free play of the trip-arm against the resistance-dog and camlug in the ensuing tripping action.

In some respects the improvements above described resemble those made the subject matter of Letters Patent granted me on the 28th day of June, 1892, No. 477,992, but in the present instance there vare fewer active parts than in the device shown in said patent, and they are concentrated near the center of the binder instead of being scattered apart from each other with intermediate connecting shafts.

It will be understood that terms ot' position in the above description, such as front and rear, or in and out, are used only in a relative sense, and not as terms of limitation.
